- • Best for: Layering for outdoor activities, workouts and cosy sleepwear on cold nights
- • Not ideal for: Wearers in hot climates or those who prefer natural fibres
Made from a 95% polyester and 5% spandex blend with fleece lining for warmth. Moisture-wicking and breathable construction helps reduce clamminess during activity.
Warmth without bulk - thanks to a fleece-lined polyester-spandex blend
Composition is 95% polyester and 5% spandex with an inner fleece lining that traps air to retain heat. The fabric fits close to the body to reduce heat loss while avoiding bulky layering.
Reliable insulation keeps core temperature steadier during chilly commutes or outdoor sessions without adding bulk under clothing.
Stay dry during activity - with a moisture-wicking, breathable fabric
A moisture transport system in the synthetic fibres wicks sweat away from the skin and allows airflow through the knit. Breathable construction helps evaporate sweat to limit a clammy feeling.
Comfort is maintained during runs, cycling or indoor workouts because perspiration is moved away quickly and drying is faster.
Free movement and durability - with four-way stretch and reinforced seams
Four-way stretch delivers full mobility while strong seams reduce the risk of premature tearing, and the design is described as squat-proof. Stretch fibres return to shape after movement.
Freedom to stretch, bend and layer without restrictions, and durability that stands up to regular activity and frequent wear.
